Cosmopolitan reports that, when compared with standard white bread, rye contains four times the amount of the fiber that encourages weight loss. Rye bread also contains 20-percent less calories than standard white bread. Dieting programs designed to help people lose weight have included rye bread among their recommended foods.
Rye bread is 100 percent wheat-free and is a whole grain, which is a source of fat-soluble antioxidants. The World's Healthiest Foods points out that flours derived from rye also hold on to more of the important nutrients that wheat flours lose during refining. In addition to being better for human health, rye bread also boasts a full and robust taste.
